SAFE R VAULT DOOR.

i SPECIFICATION forming part of Letters Patent No. 713,879, datedvNovember 1.8, 1902. l Application filed March 6| 1902. Serial Nol 96 ,872. (No model.)

reaching ofthe boltwork by electrical appa' ratus will be rendered so difficult that its accomplishment will bea practicable impossibility.

' A further object of the invention is to proL vide an improved organization in which the means for resisting electrical attacks is to a certain extent maintained in position by the zo bolts carried by the door.

In the drawings accompanying and forming a part of this specification, Figure l is al perspective view, -partly in section, of the` rear side ofl a door. Fig. 2 is a transverse sectional view of such door, `and Fig.3 is a perspective view of one of the wedges.

Similar characters of reference indicate corresponding parts in the different figures of the y, drawings. 3o A This improved .door in the form thereof herein shown and described may be similar, if preferred, to any of those heretofore patented by me, in which case it would comprise a body portion 2, havinga rearwardly-extending integral ange 3, provided with the usual oset or step 4, and bolt-openings 5 for the bolts 6, which are shown as radially located,

'the door being of circular formation. Any

suitable means may be used for throwing the 4o bolts into and out of their protracted positions-such, for instance, as gearing,I one member of which, as 7, is located on a stud 8,

supported by a back plate 9, secured yto the l flange of the door, and to which gear member the bolts are pivted at their inner ends for swinging movement as they are longitudinally projected or withdrawn.

In practice the bodyof the door `and its flange will be made or cast of unmachineable 5o metal-such, for instance, 'as manganese4 i door blown out.

steel, which, as is wellknown, itis not possibleto drill orfcut. Consequently it has not been found practicable to drill or cut into the door for the purpose of reaching the bolt-V work by any of the usual means known to the 5 5 burglar. It has been suggested', however, that by means of an electric arc an opening might be drilled through the doorsheretofore patented by me and by means of .this openin g the boltwork manipulated or nitroglycerin inserted and theI boltwork blown off or the The use of nitroglycerin, however, would not be practicable," as there would be no way to prevent its running away,

so that it could not be tired, this having 'y proved' to b'e'fthe casewhen nitroglycerin was inserted through the opening after the combination -lock spindle was removed. Furthermore, even if it could be-Iired `the organization is such that the back plate and 7o thebolt-operating mechanism only would be blown inwardly, it being impossible to blow the bolts out of position or the door outwardly thereby unless such anamount be used as would wreck not only the safe, but l its contents and the building in which it was placed. So far as I am aware, this electrical attack has not yet been successfully tried in a l burglarious manner and in my opinion could not be successful except under the Amost fa-"Bo vorable and exceptional circumstances,owi`n g to difficulties which the burglar would find impossible to overcome. 'I he objectpf the present invention, therefore, is to provide means which will render such attacks impracticable even under the most favorable and exceptional circumstances and to make such attacks impossible within the time which the burglar usually has to devote to the operation of opening the safe or vault, and for 9o this purpose I have provided means which will prevent the use of the electric arc for the purpose of drilling a hole through the door suiiiciently to permit the boltwork to be reached even should, under the most favorable and exceptional circumstances, the door be drilled in this manner. This means in thev present instance comprises a member or plate 10, usually corresponding in shape and material to that of the door, and therefore 4shown ro as ef circular 'formation'embedded in suitable non-conducting material 12-such, for

instance, as cement and sand disposed in *aI 'I "chamber 13 in the rear of the door-and which ducting fte he overcome in and properly.

material and plate are held in position by suitable means-such,-for instance, as a plate 14, (designated herein as the chamber-form 'Eng plate, since it forms with the door-body 2 a chamber 13.) Should the l,burglar be successful in drilling by means of an .electric arc through 'the body of ythe door, the noncon ducting material will interrupt the use of the arc, endif furtherattempt is made to reach the belts by the ordinary tools the manganesestecl plate 10, -embedded Within the nonconmaterial, would lprevent this. Gonesqnently th'e diifculties which would have any attempt to reachthe lreitworlr would require so much time and labor that even under the most favorable and exceptional circumstances a burglar would dnd it impossible to accomplish his object.

in the presentinstauce this plate 14 lcarries the bearing-surfaces 16 for the bolts. These haveheretoforebeen placed on the body 2 of the door and have, owing to the material of which the door was composed,necessitated considerable work ingrinding such surfaces 'injorder that the bolts may work smoothly By locating these surfaces on this plate`14, which may be of ordinarysteel, they can be -formed'with less time and labor than heretofore. This plate 14 also carries a centrally-located boss 16', with which the inner ends of the b'olts engage when' in their protracted positions, so that the possibility of withdrawing the bolts except by swinging thorn radially is prevented. This plate 14 may be maintained in position in various ways; but in the present instance it is bolted at the center thereof to the body of the door, Which for this purpose is provided with a boss having a soft-metal insert 17 cast there- .in for the reception of the bolt. For securplate throughout their entire length also tend their protracted positions, since the strain thereof will be received by this plate--that is to say, lthe load being at the points or and the fulcrum at the pointsb the power will bel applied at the points c to the plate 14, whereby it is pressed toward the body of the door.. Moreover, it will be seen that this organizationl provides a multiplated door, be-

to bold the plate in position when they are in tween which plates and the back plate the bolts' are located, thus affordingadditional security to such lbolts 'and their operating mechanism. It will also be seen that should a burglar working under .extremely favorable and exceptlonal circumstances be successful in drillingby-means of the arc through the bodyof the safe-door his further progress would bel intercepted and practically prevented ,by 'the non-conducting material,

since this will prevent the formation-of the are, and consequently the further drilling by this means through the door. Before he could proceed further it would be necessary to remove a considerable portion of the nonconducting material, after which he would still have to penetrate thev manganese-steel plate, and the possibility of using an electric arc through such plate while the non-conducting material is surrounding the same'is not believed to be practicable.

It will be seen that in the present. structure the plate 10 is independent of the door-body and its iiange--that is to say,

suspended free of connection therewith at all points, except through the medium of the insulating ma.- terial-fandis-therefore in what may be designated a floating condition.
